Answer:
Time = 0.3256 sec
Explanation:
Velocity = displacement / time
43=14/t
So the time =14/43
t=0.3256 sec
Answer:
True
Explanation:
Stellar-sized black holes form when a star explodes in a supernova is a true statement. Supernova occurs when a huge size star collapses into itself. This explosion is massive such that parts of the stars are thrown apart. And this phenomenon gives rise to super massive black holes. Supernova occurs when the core becomes very heavy and star is not able to hold its won weight.

Answer:
Unit of energy is kg-m/s or Joules.
Explanation:
The mass- energy relationship in physics is given by :
Where
m is the mass of the object
c is the speed of light
The SI unit of m is kilogram while the SI unit of c is as same as speed of light i.e. m/s. So, the unit of energy is kg-m/s. It is also equivalent to Joules.
So, the SI unit of energy is kg-m/s or Joules. Hence, this is the required solution.
Helium lithium and calcium
